(to be) The Best Geospatial Software Engineer
Software Engineer with 8+ years of experience delivering high-impact projects for tech companies and government clients. Specializing in Fullstack Development (React, Next.js, FastAPI), Mobile Development (React Native), and Geospatial Applications (Mapbox, PostGIS, CesiumJS).
Enhancement through third-party system integration
Performance improvements in production applications
Reduction in delivery time and production costs
Reduced through CI/CD pipeline implementation
At the outset of my journey in Geomatics, I wasn't just absorbing the foundational knowledge of geospatial science, but also cultivating a passion for technical solutions. From this point, my journey as a software engineer commenced.
Data visualization isn't confined to just maps. As I delved into Frontend Engineering, I realized that data could "speak" in numerous forms – tables, charts, lists, cards, and more. I mastered the art of presenting data in the most effective and captivating ways.
A stellar spatial solution requires a robust data foundation. From the backend, I built, optimized, and integrated systems to ensure data is delivered swiftly and accurately. From spatial operations to crafting responsive APIs, I'm the architect behind the visuals you witness.
With the knowledge I garnered from Geomatics to Computer Science, I've bridged these two worlds. I'm not just any software engineer; I am a spatial software engineer. This unique expertise empowers me to offer integrated and holistic solutions for your geospatial needs.
Browser-first geospatial tools built with modern web technologies
Built GeoMatcher, is a privacy‑first, browser‑only geospatial data matching tool that cleans and joins messy CSV/Excel location columns to administrative boundaries. It uses DuckDB WASM for in‑browser analytics, a three‑tier matching engine (exact, semantic, fuzzy), spatial point‑in‑polygon, and exports crosswalks to CSV/Excel/GeoJSON—no server required.
Built a free, lightweight, browser-only WebGIS alternative to QGIS. Geoverse combines DuckDB WASM spatial SQL, MapLibre GL mapping, and a React/TypeScript UI for dataset management, table views, spatial operations, and multi-format export.
Built GeoConverter, a browser‑based geospatial file converter that runs GDAL/OGR in WebAssembly for fully local, privacy‑first processing. Supports 30+ vector formats, CRS reprojection, geometry/attribute filtering, simplification, and format‑specific optimizations, delivered through a modern React + Vite UI.
Built a lightweight, browser-based semantic search app that runs fully client‑side using PGlite (PostgreSQL WASM) and Transformers.js. It ingests PDFs/Markdown/text, chunks and embeds content in‑browser, and combines semantic + keyword search with dual highlighting. All data stays local in IndexedDB, with fast HNSW vector search and no server required.
All my projects are free and open-source. If you find them useful, consider supporting their development and maintenance. Your support helps me dedicate more time to building innovative geospatial tools for the community.
